2 Safety
2.1 General safety precautions for power tools
WARNING! Read all safety precautions and other instructions. Failure to observe the safety
precautions and other instructions may result in electric shock, fire and/or serious injury.
Keep all safety precautions and instructions for future reference.
Working area safety
▶ Keep your working area clean and well lit. Cluttered or dark working areas can cause accidents.
▶ Do not operate the power tool in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
▶ Keep bystanders, children and visitors away while operating the power tool. Distractions may cause
you to lose control of the tool.
Electrical safety
▶ Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶ Do not allow your body to come into contact with grounded surfaces such as pipes, radiators,
ovens and refrigerators. There is an increased risk of electric shock if your body is grounded.
Personal safety
▶ Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating the power tool may result in serious personal injury.
▶ Adopt the correct posture when working. Maintain proper footing and balance at all times. This
will allow you to control the power tool better, even in unexpected situations.
▶ Wear your personal protective equipment and always wear protective glasses. Depending on the
type of power tool you are using and its purpose, wearing safety equipment such as a dust mask,
slip-resistant safety shoes, a hard hat or hearing protection will reduce the risk of injury.
▶ Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair may be caught in moving parts.
▶ Avoid starting the tool accidentally. Make sure that the power tool is switched off before connecting
it to the battery and before picking it up or carrying it. Carrying power tools with your finger on the
switch or plugging in power tools that are already switched on may cause accidents.
▶ Remove accessory tools or wrenches before switching the power tool on. An accessory tool or a
wrench left attached to a rotating part of the power tool may cause personal injury.
▶ If devices are provided for connecting dust extraction and collection equipment, make sure these
are connected and used correctly. The use of a dust extraction system can reduce dust-related
hazards.
Using and handling the power tool
▶
Do not overload the tool. Use the correct power tool for your application. The correct power tool
will do the job better and more safely within the performance range for which it is designed.
▶ Do not use a power tool if it has a faulty on/off switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
▶ Remove the battery from the power tool before making any adjustments, changing accessories or
storing the tool. This precaution reduces the risk of the power tool starting accidentally.
▶ Store power tools out of reach of children when not in use. Do not allow persons who are not
familiar with the tool or these instructions to operate it. Power tools are dangerous in the hands of
untrained users.
▶ Maintain power tools properly. Check that moving parts are in correct working order and do not
jam, and check whether any parts are broken or so damaged that correct operation of the power
Printed: 27.07.2016 | Doc-Nr: PUB / 5293001 / 000 / 00
3
tool cannot be guaranteed. If any parts are damaged, have these parts repaired before using the
tool. Many accidents are caused by poorly maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to jam and are easier to control.
Using and handling the cordless power tool
▶ Use only the specified batteries in the power tools. Use of any other batteries may present a risk of
injury and fire.
▶ Recharge the batteries only with the chargers specified by the manufacturer. A charger that is
suitable for a certain type of battery may present a risk of fire when used with other types of battery.
▶ When the battery is not in use, keep it away from other metal objects such as paper clips, coins,
keys, nails, screws, or other small metal objects that could cause bridging between the terminals.
A short circuit between the battery terminals may cause burns or a fire.
▶ Liquid may leak from the battery if used incorrectly. Avoid contact with this liquid. Liquid leaking
from the battery may cause skin irritation or burns. If contact accidentally occurs, rinse with water. Seek
medical attention if the liquid comes into contact with the eyes.
2.2 Additional safety precautions for screwdrivers
Personal safety
▶ Only use the product if it is in perfect working order.
▶ Never tamper with or modify the tool in any way.
▶ Use the auxiliary grip supplied with the tool. Loss of control can cause personal injury.
▶ Always hold the power tool with both hands on the grips provided. Keep the grips clean and dry.
▶ Hold the power tool by the insulated gripping surfaces when performing an operation where the accessory
tool may come into contact with concealed wiring. If the accessory tool comes into contact with a live
wire, metal parts of the power tool may also become live, causing the operator to receive an electric
shock.
▶ Avoid touching rotating parts – risk of injury!
▶ Wear suitable protective glasses, a hard hat, ear protection, protective gloves and light respiratory
protection while using the tool.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of
wood and concrete/masonry/stone containing quartz, minerals or metal may be harmful to health.
▶ Make sure that the working area is well ventilated and, where necessary, wear a respirator appropriate
for the type of dust generated. Contact with or inhalation of dust may cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust, such as oak and beech
dust, are classified as carcinogenic, especially in conjunction with additives for treating wood (chromate,
wood preservative). Materials containing asbestos may only be handled by specialists.
▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
Electrical safety
▶ Before starting work, check the working area for concealed electric cables or gas and water pipes. If
you damage an electric cable accidentally, external metal parts of the power tool may become live and
present a risk of electric shock.
Careful handling and use of power tools
▶ Switch the power tool off immediately if the accessory tool jams. The power tool may go off course and
veer to the side.
▶ Wait until the power tool has come to a complete stop before setting it down.
2.3 Careful handling and use of batteries
▶ Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not take apart, squash or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not attempt to charge or continue to use damaged batteries.
